Despite the limited power available in a battery-operated hand-held device, a display system must still have an enough resolution and sufficient color depth to deliver the necessary information. We… (More)

Thin-film transistor liquid-crystal displays are systems widely used to support full-featured multimedia. For such systems, backlight is a major source of power dissipation. This article introduces a… (More)

Memory systems are dominant energy consumers, and thus many energy reduction techniques for memory buses and devices have been proposed. For practical energy reduction practices, we have to take into… (More)

We describe a Web-based energy estimation tool for embedded systems. An interesting feature of this tool is that it performs real-time cycle-accurate energy measurements on a hardware prototype of… (More)

In this paper, we introduce a precise energy characterization of SDRAM main memory systems and explore the amount of energy associated with design parameters, leading to energy reduction techniques… (More)
